Middleware Mediated Semantic Sensor Networks

Abstract

This paper investigates how the Internet of Things (IoT) can take advantage of Semantic Technologies when combined with a prototyping middleware. Although Sensor Networks within the IoT offer enormous potential, the surprising variability in terms of communication and interoperability among Things is a challenging problem. This paper proposes to move from the classic meaning of Sensor Networks to the concept of Semantic Sensor Networks. The proposed methodology uses Semantic Web technologies, based on machine-interpretable representation formalisms, for combining Sensor Networks and the Paraimpu middleware. We propose to prototype and deploy a Semantic Sensor Network, focusing on the semantic aspects, with the tangible advantage to delegate to Paraimpu the low-level network operations. As a result we obtain a shared RDF Knowledge Base useful for improving integration and communication between different networks.
